    摘要： A diamond cutting tool has a rake face (5) of a cutting edge member (2) consisting essentially of a (111) plane of diamond. The cutting edge member (2) of diamond is vapor-deposited by CVD or the like on an independently prepared base material. In this vapor deposition, the diamond is deposited while controlling and periodically varying the carbon to hydrogen ratio of the supplied raw material gas, in such a manner that a (111) crystal plane is oriented with a prescribed fluctuation or non-uniformity, but is substantially parallel to the base material surface. The as-formed diamond material is separated from the base material and cut into a desired shape, and then bonded as a cutting edge member (2) to a tool base (1) through a metallization layer (4) and a brazing layer (3), in such an orientation that the (111) plane defines the rake face (5). The tool having such a rake face (5) consisting essentially of the (111) plane, with a prescribed fluctuation of its orientation, is excellent in wear resistance and is resistant to cleavage damage.

    摘要： A bonding tool has a head portion made essentially of vapor-deposited diamond, wherein a principal diamond crystal plane forming a head face is a (111) plane. Such a head face has high hardness and a good wear resistance. In order to improve the toughness of a bonding head which is mainly made of vapor-deposited diamond, a portion or ply forming the head face consists essentially of high-purity diamond, and another portion or ply supporting the head face consists essentially of low-purity diamond. The head face has a high rigidity, while the portion supporting the head face has a high toughness. In order to provide a bonding head portion which is mainly made of vapor-deposited diamond with electrical conductivity, a first portion or ply forming a head face consists essentially of polycrystalline diamond containing a relatively small amount of dopant, and another portion or ply supporting the first portion or ply contains a large amount of dopant. The head portion having electrical conductivity can be heated by energization. In a tool employing a coating containing vapor-deposited diamond as a bonding head portion, the coating is formed by a compound of a metal or ceramics and vapor-deposited diamond, in order to improve the strength of the coating and adhesion to a tool substrate.

    摘要： A diamond cutting tool has a tool substrate and a cutting edge member. The cutting edge member is formed of a material having a three-layer structure or a diamond composite material. When the material having a three-layer structure is employed, the cutting edge member is formed by a vapor-deposited diamond layer defining a rake face, a layer of a composite material of vapor-deposited diamond and a metal or ceramics, and a layer of the metal or ceramics. The metal is prepared from Mo, W, Cr, V, Nb, Ta, Co, Ni or Fe, while the ceramics is prepared from cBN, SiC, Si.sub.3 N.sub.4, WC, TiC, TaC, NbC, Cr.sub.3 C.sub.2, Mo.sub.2 C, VC, TiN or BN. The cutting edge member is brazed to the tool substrate through the metal or ceramics layer. When the diamond composite material is employed, on the other hand, the cutting edge member is formed of a composite material of particles or fibers of AlN, cBN or SiC and vapor-deposited diamond. The diamond cutting tool is excellent in heat resistance and durability.
